Description

This comforting Chicken and Biscuits recipe combines a hearty chicken and vegetable filling with fluffy, cheddar-infused biscuits baked on top. Perfect for a family dinner, the dish offers savory flavors and a satisfying texture contrast between the tender filling and golden biscuits.


Ingredients

Chicken Filling

  • 2 tbsp unsalted butter
  • 1 medium onion, chopped
  • 2 cloves garlic, minced
  • 2 cups sliced mushrooms
  • ⅓ cup all-purpose flour
  • 2 cups low-sodium chicken broth
  • 1 cup milk (whole or 2%)
  • 1 tsp fresh thyme leaves
  • Salt & black pepper, to taste
  • 3 cups cooked chicken, shredded or diced
  • 2 cups frozen mixed vegetables (peas, carrots, green beans, corn)

Biscuits

  • 2 cups all-purpose flour
  • 1 tbsp baking powder
  • ½ tsp baking soda
  • 1 tsp salt
  • 6 tbsp cold unsalted butter, cubed
  • ¾ cup cold buttermilk
  • ½ cup shredded sharp cheddar cheese
  • 2 tbsp chopped fresh parsley (optional)


Instructions

  1. Prepare the Chicken Filling: Preheat the oven to 400°F (200°C) to ensure it’s ready for baking the casserole later.
  2. Sauté Onion: In a large skillet, melt 2 tablespoons of unsalted butter over medium heat. Add the chopped onion and cook for 3-4 minutes until it becomes soft and translucent.
  3. Add Garlic and Mushrooms: Stir in the minced garlic and sliced mushrooms. Continue cooking for about 5 minutes until the mushrooms are tender.
  4. Thicken the Mixture: Sprinkle ⅓ cup of all-purpose flour over the vegetable mixture and stir constantly for 1 minute to cook out the raw flour taste.
  5. Add Liquids: Gradually whisk in 2 cups of low-sodium chicken broth and 1 cup of milk, then simmer for 5-7 minutes until the filling thickens into a creamy sauce.
  6. Season and Add Chicken & Vegetables: Stir in fresh thyme leaves, salt, black pepper, the shredded or diced cooked chicken, and 2 cups of frozen mixed vegetables. Cook for another 2-3 minutes to heat through.
  7. Transfer Filling: Pour the prepared chicken mixture into a greased 9×13-inch baking dish, spreading evenly.
  8. Make the Biscuits: In a medium bowl, whisk together 2 cups flour, baking powder, baking soda, and salt. Cut in 6 tablespoons of cold cubed unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs.
  9. Add Cheese and Parsley: Stir in ½ cup shredded sharp cheddar cheese and 2 tablespoons chopped fresh parsley (if using).
  10. Add Buttermilk: Make a well in the center of the dry ingredients and pour in ¾ cup cold buttermilk. Stir gently until just combined, being careful not to overmix to keep the biscuits tender.
  11. Top the Filling: Drop spoonfuls of the biscuit dough evenly over the chicken filling in the baking dish, leaving small gaps for even baking.
  12. Bake: Place the casserole in the preheated oven and bake for 25-30 minutes until the biscuits on top are golden brown and the filling is bubbly.
  13. Rest and Serve: Allow the dish to rest for 5 minutes out of the oven before serving to let the filling set slightly and cool to a safe temperature.

Notes

  • Use cold butter and buttermilk for tender, flaky biscuits.
  • Do not overmix biscuit dough to avoid tough biscuits.
  • Frozen mixed vegetables add convenience and color, but fresh veggies can be substituted if preferred.
  • Leftover cooked chicken works well; rotisserie chicken is a great shortcut.
  • This dish can be reheated in the oven to restore biscuit crispness.
